Looks like a Quarter horse to me.
Ewe neck, Hammer headed, steep shoulder, knife withers, down hill build, very steep croup, long stif looking coupling, fery upright hind pasterns, nice low and large hocks, adequate bone, ccorrect front leg.
All that being said, he is groomed very nicely and I would guess he has a good disposition.
There is something about the outside of a horse that is good for the inside of a man. ~Winston Churchill
